Turning a WhatsApp chat into a PDF
There are three real routes and they produce very different objects. Print-to-PDF from your computer is free and ugly. A web viewer is prettier and asks you to upload the chat. A typeset book file is print-ready to the millimetre and costs money. Which is right depends entirely on whether the PDF is for reading, for keeping, or for handing to a print shop.
| Print-to-PDF yourself | A web viewer | A typeset book file | |
|---|---|---|---|
| Cost | Free | Free to paid | Paid, per book |
| Looks like | Courier text on A4 | Bubbles, on screen | Bubbles, laid out for paper |
| Photos | Only if you insert them by hand | Usually yes | Typeset in place |
| Voice notes | A line of text | A player, or a QR code | A waveform with the real length |
| Page size | Whatever your printer says | Usually A4 | Exact A4, A5, A6 or 21 cm square |
| Cover and spine | None | None | Wraparound, sized to your page count |
| A print shop can bind it | Badly | Poorly | Yes, same day |
| Your chat is uploaded | No | Yes | Yes, and deleted within 48h |
So which should you pick?
If you want to read or archive the conversation, print-to-PDF is genuinely fine and costs nothing — do that and stop reading. If you want something that will be bound into an object someone opens in ten years, none of the free routes produce a file a printer can use: page geometry, bleed and a spine sized to the page count are the whole job, and they are the part that is missing. Pick by what happens to the file next, not by the word “PDF”.
Route one: print-to-PDF, free, right now
Nothing gets uploaded anywhere and it takes two minutes. It is the correct answer more often than anyone selling a service will admit.
- Export the chat and unzip itWithout media is fine here. Opening the file if you have not done it before.
- Open the .txt in any editor or browserDragging the txt into a browser tab works and gives you the cleanest margins.
- Ctrl/Cmd + P → Save as PDFChoose “Save as PDF” as the destination rather than a printer.
- Accept what it looks likeMonospaced, no bubbles, a timestamp in front of every line, no photos. It is a transcript. For a legal record or a personal archive that is exactly right; for a gift it is not.
Once you have that PDF, the free tools on this site will do the printing hard parts in your browser: fold it into a booklet, impose it two-up for a duplex printer, or add the blank pages duplex needs. Nothing uploads — the same promise route one makes.
Route two: a web viewer
Several free sites will render an export into something bubble-shaped in the browser. They read nicely and they are quick. Two things to weigh: you are uploading a private conversation to a service whose retention policy you have probably not read, and the output is a screenshot of a screen — pages sized for a monitor, images at screen resolution, type that goes soft the moment it is inked onto paper. Fine for reading. Not a book.
Route three: a print-ready file
This is what Kept in Print sells, so treat the next paragraph accordingly. The difference is geometry: every page is exactly A4, A5, A6 or 21 cm square, the type is real type rather than a picture of type, images sit at print resolution, and the cover wraps with a spine measured to your actual page count. That is the specific set of things a print shop needs and no free route provides — and it is why the file is the product, not the parcel.
You can build the entire book and read every page before paying anything. The free version is the whole thing with a faint mark across each page — nothing hidden, nothing blurred.

Your exact number depends on how long your chat is. Slide the calculator to your chat’s size, or drop your export in and let the studio count the pages for free.
Questions people actually ask
Can I convert a WhatsApp chat to PDF for free?
Yes. Export the chat, open the .txt file in a browser or text editor, and use your operating system's Print → Save as PDF. Nothing is uploaded anywhere. The result is a plain transcript without bubbles or photos.
Why won't a print shop accept my PDF?
Usually page geometry. Shops need pages at an exact finished size with consistent margins, and a cover whose spine width matches the page count. A PDF printed from a browser has none of that, and a shop will either refuse it or bind it badly.
Does the PDF include photos and voice notes?
Print-to-PDF does not — you would insert images by hand. A typeset book file places photos and stickers in the conversation where they belong, and prints voice notes as a waveform showing their real duration.
Is uploading my chat to a viewer site safe?
That depends on the site and you should read its retention policy before deciding. If you would rather not upload anything at all, the print-to-PDF route keeps the file on your own machine from start to finish.
What page size should the PDF be?
A5 is the usual choice for a chat book — it is close to a paperback and keeps the bubbles at a comfortable reading size. A4 is cheaper to print in some places but reads like a report.
